You never qualified what you NEED in a calculator. If it is a similar form factor, feel and quality of the Hp 42s, the Hp 17Bii is you best physical replacement. Also has long variable names and an extremely easy solver to use. The stats functions are actually superior as its stats are list based.
If you need trig, two line display and programming, the Hp 35s is you your other solution. The programming accesses 32K of RAM but is limited to only single name variables and address numbers. In some ways, the Hp33s (aside from an ugly keyboard and no address lines) has a better keyboard with a better handling of Rect to Polar conversions and HEX,BIN,DEC conversions.
I have both, and while I like the look of the Hp35s better, I preferr to use the Hp33s. Better size and the R->P seals the deal for me. The Hp35s is nearly the physical size of a graphics calculator. It is not really a true pocket calculator.
Hp is just releasing an Hp 30B which you might also consider, but beforewarned, it has only a meager 130 keystroke steps. Not sure if you can segment these out to several programs or not. Looks to be a promising calculator, but is optimized for the business user first so that trig is buried under menus, still a better option than the Hp 17bii if you do need trig though.
Sadly, the only true replacement for an Hp42s is another Hp42s. There is not yet a superior or even close replacement. If I had to replace my Hp42s and didn't have my spare, I would then use an Hp48g over the present offerings.
Currently I am in a Graduate design course and I use an Hp50G and it is fast and has lots of bell and whistles, but I still like my Hp48g better and am seriously considering stepping down to the Hp 48g(ok, +) even though it is lots slower. I just like the keyboard and the number crunching layout BETTER! Knowing this I hesitate to tell you to upgrade to any newer Hp graphics. While they have improved their keyboards and their prices are actually less than their Ti counterparts, they still don't have that old Hp feel that an Hp 48g would probably give you. And while an Hp 48g isn't a pocket calculator, if your Hp 42s sat on your desk, an Hp 48g would probably sit on your desk just as well.
